Mostly Good.
The host is kind and courteous and has done a lot to make the place as nice as can be. Fantastic noise insulating glass to the balcony (couldn't really hear the traffic at all), great bed, wonderful pillows (I a so inspired I am going to buy one just like it), nicely decorated, modern, warm, friendly, good TV, good internet speed. Very comfortable.
The complex has a great restaurant in it that serves REALLY good food at a reasonable price. The location is close to downtown (100 baht by grab) and close to icon siam (100 baht by grab).
The less good - the apartment is extremely compact (you have to balance this against the price of course, which is excellent). There is a nice gym but it is not included, there is an infinitely less nice gym in a basement very sparsely populated with equipment that is free. So if the gym is important to you, as it is to me - be warned.
Her check in procedure is ridiculous. Ask her to get someone to meet you with the key. I do not think it is reasonable that one has to travel over a kilometre to pick up a key to check-in.
I'd like to finish on a positive note because I think that mostly Kara did everything in her power to make our stay a good one and has put a lot of thoughtful touches into her property that others do not always do. So my positive ending is that the staff at the condo complex are VERY friendly, VERY helpful and VERY kind.
Overall, it was a nice stay at an excellent price. You could do a lot worse.
